Half of an antipodal spherical design
TL;DR: In this paper, the authors investigate several antipodal spherical designs on which we can choose half of the points, one from each antiphodal pair, such that they are balanced at the origin.

Classification of Partially Metric Q-Polynomial Association Schemes with $$m_{ 1} = 4$$ m 1 = 4
TL;DR: In this article, the authors classify Q-polynomial association schemes with respect to the nearest neighborhood relation as partially metric with respect of the relation under a certain ordering of the relations.

The complex conjugate invariants of Clifford groups
TL;DR: The purpose of this paper is to show that very similar results can be obtained for the invariants of the complex Clifford group X m acting on the space of conjugate polynomials, and shows that the dimension of this space is 2.
